characters on the drawing representing like i parts.

This invention relates to automatic filling replenishing looms whereinthe running filling is replenished prior to complete exhaustionandwherein the old or spent filling is parted between the cloth and theshuttle by a clamping and parting means mounted upon a carrier, such asthe usual swinging shuttle feeler, so as to be moved bodily,

rearwardly and forwardly or toward and from the lay.

The object of the invention is to provide an improved,.simple andeffective mechanism of that type in which the filling clamping andparting device is operated when,

and only when, a fresh filling carrier is transferred from themagazineor hopper to the lay.

The object of the invention is further to provide a construction inwhich the opera tion of the filling clamping and parting device issecured by a striker arm movable with. the filling carrier support andacting to close the filling clamping and parting de vice when inoperative position and yieldingly movable with respect to the fillingcarrier support upon the occurrence of an abnormal resistance.

Theobject of the invention is further to provide a construction in whichthe desired results are secured by a filling clamping and parting devicehaving its movable member brought into closing position by an up-' wardmovement of its efiective end.

These and other objects and features of the invention will appear morefully from the accompanying description and drawings and will beparticularly pointed out in the claims. I l

The drawings illustrate the invention as embodied in a preferred form ofthe well known Northrop type of automatic filling replenishing loom.Such a type of loom together with filling clamp ng and parting mechanismof a generally similar object and indication of that Specification ofLetters Patent.

purpose is shown in the patent to Davis, 1,084,878, granted Jan. 20,1914:.

In the drawings:

Figure l is a transverse section of a portion of an automatic fillingreplenishing loom with a preferred form of the present inventionembodied therein.

Fig. 2 is a detail showing the position of the filling carrier supportand connected parts and the filling clamping and parting device when inoperative position ready for transfer of a fresh filling carrier fromthe magazine to the lay,

Fig. 3 is a top plan view of the construction shown in Fig. 2.

The construction and operation of the automatic filling replenishingloom herein illustrated being well lznown and familiar to those skilledin the art and the patent to Davis above mentioned showing aconstruction securing the same broad result as that here secured, itwill be necessary to describe indetail only those features and theiroperation immediately concerned with the present invention.

The loom frame 1 supports the magazine or hopper Econtaining the supplyof fresh filling carriers herein shown as bobbins 3. men the runningfilling in the shuttle 4 on the lay 5 has become substantiallyexhausted, fact is transmitted through a well known mechanism to the rodor rock shaft 6 which is thereupon rocked to raise the arm 7 and swingthe shuttle feeler 8 rearwardly and atthe same time to raise the dog 9connected to the transferrer 10 into the path of a hunter 11 on the lay.If the shuttle is properly boxed,

allowing the shuttle feeler to pass the end of the shuttle, then thehunter l1 striking the dog 9 swings the transferrer l0 down wardlyforcin a fresh filling carrier 3 from I nected to the pivot 14 whichextends to the front or opposite side of the magazine and is thereprovided with an arm 15. This arm is provided with a notch 16 fittingover a pin 17 and resting against the head 18 of the pin. This pinslides through a notched or slotted lug 19 projecting from the hopper 2and a helical spring 20 surrounds the pin between this lug and itsopposite head 21. Thus the pivoted or swinging support 13 is normallyheldin the position illustrated but may move or swing downwardly againstthe tension of the spring 20 when the transfer-of thefresh fillingcarrier takes place. It is this device which is utilized to secure theoperation of the filling clamping and parting device when, and onlywhen, a fresh filling carrier is transferred from the magazine to thelay.

The shuttle feeler 8 acts as a carrier for the filling clamping andparting device. In the present invention this device differs from thefamiliar form, shown for example in the above mentioned patent to Davis,in that the movable blade or member 22 pivoted at 23 to the shuttlefeeler swings upwardly at its rearward or effective endto close upon theco-operating elements of the device and clamp and part the filling. Therearward end of the shuttle feeler is also at its lower edge beveled orinclined upwardly as shown at 2 1 to insure the filling, extending fromthe'shuttle to the fell, being guided into the field of action ofthefilling clamping and parting device.

The general operation is a familiar one. Upon the call for fillingreplenishment, the shuttle feeler 8 is swung rearwardly, the movableblade 22 is swung to open position and in this position the fillingclamping and parting device passes over the filling extending from thesubstantially exhausted filling carrier to the fell. The movable bladeis then swung to closing position parting and clamping the filling andthen when the shuttle feeler swings forwardly the clamped end of thefilling is carried forwardly so as to bring the filling into the path ofthe usual temple thread cutter.

The present invention is concerned particularly with the means forclosing and opening the filling clamping and parting device.

The arm 15 which is rigidly connected to and swings with the fillingcarrier support 13.is provided with a laterally extending stud 25. An Lshaped striker arm 26 is provided with a hub 27 which fits over the stud25 and is held in place by a washer 28 and a pin 29 extendingtransversely through the end of the stud 25. A helical spring 30surrounds the stud 25 in the interior of the hub 27 and is secured atone end 31 to the arm 15, while the other end 32 extends out throughfthehub and rests on top of the arm 26 and beneath a guiding flange 33. Thestriker arm 26 at its rear edge is provided. with a longitudinallyadjustable set screw 34iabutting against the lower end of the pin 29. Itwill thus be seen that the spring 30 holds the striker arm with the setscrew 3% against the pin 29 which therefore constitutes a stop so thatthe striker arm moves with the filling carrier support 13. This springis so tensioned, however, that if any abnormal resistance occurs thestriker arm may yield with respect to the support 13 as the supportswings downwardly upon the transfer of the fresh filling carrier.

lVhen the shuttle feeler with the filling clamping and parting deviceismoved to operative position the parts are inposition as shown in Fig. 2,and it can be seen that, as the fresh filling carrier passes out of themagazine and the support 13 and striker arm 26 swing downwardly, thelatter will come into contact with the forward end of the movable blade22 and swing it into closed position thus effecting the clamping andparting of the filling. If, however, any abnormal resistance occurs tothe operation of these parts the striker arm 26 will yield against thetension of the spring 30 and thus prevent breakage or injury of any ofthe mechanism.

In order to secure the opening of the filling clamping and partingdevice when it moves rearwardly to operative position a switch cammechanism is provided. For this purpose, a bracket arm 35 secured to theloom frame extends upwardly and forwardly and at its upper forward endis provided wit-ha stud 36 and a stop lug 37. The switch cam is in theform of an inclined flange 38 formed on-the rearward end of an arm 39pivoted on the stud 36 and normally resting by gravity on the lug 37.The movable blade 22 of the filling clamping and parting device isprovided with a laterally projecting pin 10 and the parts are soarranged that when the shuttle feeler swings to forward positioncarrying the clamped and parted filling end, this pin rides beneath theswitch cam 38 raising the arm 39 which drops back onto the lug 37 afterthe pin has passed forward of it to the position shown in Fig. 1. lVhenupon the call for filling replenishment the shuttle feeler swingsrearwardly, the pin 40 rides upon the forward face of the switch cam andswings the movable blade 22 to open position as shown in Fig. 2.

There is thus provided a simple and of fective means for securing thedesired revantage in assembling and operating the cutter. By thisconstruction the parts are readily positioned so that when the movablecutter blade is actuated to close the filling clamping and partingdevice no injurious strain is placed upon the parts after the closingposition has been reached.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. An automatic filling replenishing loom comprising a lay, areplenishing magazine for the fresh filling carriers, means fortransferring a fresh filling carrier from the magazine to the lay, afilling clamping and parting device movable into position to receive therunning filling when the lay is in position for transfer, a fillingcarrier support moved by a fresh filling carrier upon its transfer fromthe magazine to the lay, and a striker arm movable with the support andacting to close the filling clamping and parting device when inoperative position and yieldingly movable with respect to the supportupon the occurrence of an abnormal resistance.

2. An automatic filling replenishing loom comprising a lay, areplenishing magazine for the fresh filling carriers, means fortransferring a fresh filling carrier from the magazine to the lay, afilling clamping and parting device movable into position to receive therunning filling when the lay is in position for transfer, a fillingcarrier sup port moved by a fresh filling carrier upon its transfer fromthe magazine to the lay, a

striker arm pivoted to swing on the support,

a stop limiting the downward movement of the striker arm with respect tothe support, and a spring interposed between the support and striker armand acting yieldingly to hold the striker arm against the stop, the saidstriker arm thus moving with the support and acting to close thefillingclamping and parting device when in operative posi tion but yieldingagainst the tension of the spring with respect to the support upon theoccurrence of an abnormal resistance.

3. An automatic filling replenishing loom comprising the constructiondefined in claim 1 in which the movable element of the filling clampingand parting device comprises a blade pivoted to the shuttle feeler withits rearward effective end swinging upwardly to effect the clamping andparting operation and its forward end, when the filling clamping andparting device is in operative position, lying beneath the striker armin position to be struck thereby upon transfer of a fresh fillingcarrier from the magazine to the lay.

In testimony whereof, I have signed my name to this specification.
